Big bank stocks have rarely been cheaper, says GMO's asset allocation team.
Two GMO is most bullish on are JPMorgan and Bank of America.
Financials-sector stocks have gotten hammered in March amid the failures of institutions like Silicon Valley Bank and Signature Bank, and as UBS hastily acquired a troubled Credit Suisse.
The eight GSIBs include: JPMorgan, Bank of America, Citi, Goldman Sachs, BNY Mellon, Morgan Stanley, State Street, and Wells Fargo.
While GMO said it couldn't comment on which seven banks it likes, it said they include JPMorgan (JPM) and Bank of America (BAC).
